Although details are sketchy, Bungie has said that cinematics are going to be as vital a part of Halo 3 as they were in Halo 2 and Halo: Combat Evolved.
"As before, they will use the game engine to keep the player feeling like a part of the action."
Although not telling you much, the trailer shows off the level of detail gamers can expect when it is launched on Microsoft's Xbox360 games console
The epic saga ends with Halo 3, the hugely anticipated sequel to the highly successful and critically acclaimed Halo 2. In this third chapter of the Halo trilogy, Master Chief returns to finish the fight, bringing the epic conflict between the Covenant, the Flood and the entire human race to a dramatic, pulse-pounding climax. If this is indeed the end for the series, the more significant issue is the death of the multiplayer community, which was somewhat wounded with changes in Halo 2 but still representes one of the largest console-based competitive FPS scenes. Timing is some time next year.
